Carbonyl selenide is a chemical compound with the chemical formula O=C=Se. It is a linear molecule that is primarily of interest for research purposes.
Properties
Carbonyl selenide is a colorless gas with an unpleasant odor.[1] Although the compound is quite stable, its solutions gradually revert to elemental selenium and carbon monoxide.[2]
Synthesis and reactions
Carbonyl selenide can be produced by treating selenium with carbon monoxide in the presence of amines.[3]
It is used in organoselenium chemistry as a means of incorporating selenium into organic compounds, e.g. for the preparation of selenocarbamates (O-selenocarbamates R–O–C(=Se)–NR'R" and Se-selenocarbamates, R–Se–C(=O)–NR'R", where R is organyl and R' and R" are any group, typically H or organyl).[3]
